HENRY O. ANDERSON, OF STANFORD, KENTUCKY.

HEMP-B RAKE.

To all whom it may concern:

Be it known that 1, Hon 141 C. Annnnson, a citizen of the United States, residing at Stanford, in the county of Lincoln and State of Kentucky, have invented certain new and useful improvements in Hemp- Brakes, of which the following is a specificatirm.

This invention relates to hemp-brakes of that kind characterized by a reciprocating series of swords which are driven past a series of stationary swords or slats on which the hemp or other fibrous material is laid crosswise.

The object of the present invention is to impart to the reciprocating swords an oscil latory movement also, so that each sword will descend alternately on opposite sides of a stationary sword, whereby the material is drawn or rubbed across the stationary swords, and the hurds more e1 ectually removed.

A. further object is to provide improved means for operating the reciprocating swords.

In the accompanying drawing, Figures 1 and 2 are side elevations taken from opposite sides and showing the parts in different positions. Fig. 3 is a sectional detail showing the mechanism for operating the reciprocating swords. Fig. a is a front elevation. Fig. 5 is a sectional detail showing the pivotal support for the reciprocating swords.

Referring specifically to the drawings, 7 denotes a suitable supportingframe in which the brake-mechanism is mounted. The stationary swords are a series of slats 8 which are set edge-up on cross-bars 9 of the supporting-frame.

The reciprocating swords 10 are mounted on a frame 11 suspended by hangers 12 from a pair of arms 13 which are pivoted at 14: to a bar 15 having at its ends trunnions 16 which are journaled in bearings 17 on a crossbar 18 at the top of the supportingframe 7. The pivots 1 1 are vertical, and the trunnions 16 are horizontally disposed, so that the arms 13 may swing in a horizontal as well as in a vertical plane.

The swords 10 are lifted by a wiper 19 into the path of which the free ends of the arms 13 extend. "When the wiper engages the arms they are lifted which operation elevates the swords 11 above the swords 8, and when the wiper clears the arms they Specification of Letters Patent.

drop down by gravity, and the swords 10 are driven between the swords 8. The wiper 19 is on a shaft 20 journaled in suitable bearings at the top of the supporting-frame T. and motion is imparted to the shaft from any suitable motive power through a beltpulley 21 on the shaft. Besides the vertical reciprocatory motion just described, the swords 10 also have a horizontal oscillatory motion, said motion being imparted to the swords by a gearing comprising a bevelgear 22 on the shaft 20 meshing with a bevel-gear 23 on a shaft 24 mounted in bearings 25 on one end of the supportingframe 7. On the shaft 2% is a crank 26 which is connected by a pitman 27 to the frame 11 of the swords 10. In order that theswords may reciprocate as already described, the connection between the pitman and the crank is by a ball-and-socket joint 28.

A set of stationary and reciprocating swords as herein described is mounted on each side of the machine but as the construction and operation is identical, the foregoing description will suifice for both sets of swords. The wiper shafts are connected by a belt 29, and the swords of one set are placed closer together than the swords of the other set and a greater number is used.

In operation the hemp or other fibrous material is laid on the swords 8 crosswise as usual, and the swords 10 are reciprocating and oscillated as already described. The swords 10 drop down between the swords 8 first on one side thereof and are then lifted and dropped down on the other side. By this dropping of the swords first into one space and then in another a rubbing and pulling action lengthwise over the material is had whereby the hurds are more effectually removed. Also a greater surface is acted on without increasing the number of swords.

1 claim:

1. In ahemp-brake having stationary swords and reciprocating swords movable toward and from the same, means for oscil lating the reciprocating swords laterally with respect to the direction of reciprocation and advancing the same alternately into different spaces'between the stationary swords.

2. In a hemp-brake having lower stationary swords and upper reciprocating swords swing in a vertical and horizontal plane, the free ends of the arms extending into the path of the wiper whereby the movable swords are swung in a vertical plane, and means connected to the drive-shaft for swinging said swords in a horizontal plane.

In testimony whereof I affix my signa 1i ture, in presence of two witnesses.
